Sugar-sweetened beverages (SSBs) are the single largest source of added sugar in the U.S. diet. In this review, we evaluate whether there is sufﬁcient scientiﬁc evidence that decreasing SSB consumption will reduce the prevalence of obesity and its related diseases. Because prospective cohort studies address dietary determinants of long-term weight gain and chronic disease, whereas randomized clinical trials typically evaluate short-term effects of speciﬁc interventions on weight change, both types of evidence are critical in evaluating causality. Findings from well-powered prospective cohorts have consistently shown a signiﬁcant association, established temporality and demonstrated a direct dose–response relationship between SSB consumption and long-term weight gain and risk of type 2 diabetes.
